Set Array List Index — Reference

Replace the item at a selected position.

Before you begin

• A Server Connect action. Create the referenced Array List earlier in the same request before using it.

Set Array List Index

Replace the item at a selected position.

Settings

Setting	Meaning
Array List	Choose a Create Array List step available above this action. The stored reference is its name; it is not a database connection or a client-side component.
Index	A zero-based item position. For example, 0 is the first item and 1 is the second. Validate it against the current Size.
Item	Fields generated from the selected list’s item schema. Supply the full new item, such as its id and name. Changing the selected list clears the previous item configuration.

Worked example

Create products with two id/name records and its item schema. Select products, set Index to 1, then set the Item fields to id 2 and name Pen. Read the list and confirm that the second record changed while the first stayed the same.

Check the behavior

This replaces the item; it is not a partial database update keyed by id. Use an existing non-negative index below Size. Out-of-range indices can create gaps or nonportable key behavior.

Return to the action workflow

Use a Get Array List Value step when you need to expose the final list after mutations. Use a database or server session when the data must persist beyond this request.

Check your result

You can configure this operation and verify the example’s resulting value or list.
